I sympathize with your reservations, but disagree with this:

"they will be abandoned eventually in favor of ones that do"

This is not what happens by default, otherwise people would have long ago abandoned Twitter, Instagram, Facebook and so on and moved to Mastodon and they would be abandoning everything now and moving to Nostr. Although that can happen it's far from guaranteed and making people aware of the problems through harsh notes is part of trying to make it happen.
